Some time ago, I made the traditional bad decision of working on my own build tool. In this case, I was interested in more efficiently sharing compilation artifacts across a dozen or so Haskell projects between two development machines without sacrificing isolation between those projects such that working on one would never break another.
GHC Development: OutsideIn
The debate around granting the government access to encrypted communications reached a new level when the Department of Justice demanded Apple help them break the encryption of an iPhone connected to a terrorist.
This article is for those familiar with Haskell and, at least passingly, with Jon Sterling's
vinyl library (that packs quite a nice introduction). Further, it is assumed that the reader is familiar with the basics of computer graphics and OpenGL. I have written another article that introduces the use of relatively modern OpenGL practice with Haskell that may serve as a primer for this article.
OpenCL is a cross-platform parallel programming standard with support for execution on both CPUs and GPUs. The OpenCL package on hackage provides a direct binding to the API with just enough Haskellosity to make invoking those API functions borderline pleasant. That said, there remains a certain amount of boilerplate that is rather offputting.
Some time ago I forked Noam Lewis's HOpenCV bindings to the fine OpenCV library to fill them out with pieces I needed for several projects at work, and to experiment with how such bindings could be used. Over time I've built up some useful components, and, in a fit of non-procrastination, I've recently pushed many updates and assembled a fun demo program.
A post on reddit linked to several implementations of a cute "Hello, world!" program demonstrating a genetic algorithm that evolves towards a target string. Example programs were written in several languages, and I thought a Haskell version could be worthwhile as it demonstrates the use of random numbers, an issue that frustrates many newcomers to the language.
